La tarea que tiene que resolver la presente invención es la creación de la aleación de 10 titanio universal con las características de resistencia y plasticidad requeridas, estructura y producibilidad de la gran gama de productos. El resultado técnico alcanzado al ejecutar la presente invención está en la regulación de la combinación óptima de estabilizantes α y β en la aleación. El resultado especificado se consigue mediante la combinación siguiente en peso en % 15 de los elementos den la aleación a base de titanio, que contiene aluminio, vanadio, molibdeno, cromo, hierro, circonio, oxígeno y nitrógeno, The task that the present invention has to solve is the creation of the universal 10 titanium alloy with the required strength and plasticity characteristics, structure and producibility of the wide range of products. The technical result achieved by executing the present invention is in the regulation of the optimal combination of stabilizers α and β in the alloy. The specified result is achieved by the following combination by weight in% of the elements of the titanium-based alloy, which contains aluminum, vanadium, molybdenum, chromium, iron, zirconium, oxygen and nitrogen,
Aluminio 4,0 -6,0 Vanadio 4,5 -6,0 Molibdeno 4,5 -6,0 Cromo 2,0 -3,6 Hierro 0,2 -0,5 Zirconio 0,1 – menor que 0,7 Oxígeno Máx. 0,2 Nitrógeno Máx. 0,05 Titanio resto Aluminum 4.0 -6.0 Vanadium 4.5 -6.0 Molybdenum 4.5 -6.0 Chrome 2.0 -3.6 Iron 0.2 -0.5 Zirconium 0.1 - less than 0.7 Max oxygen 0.2 Nitrogen Max. 0.05 Titanium rest
La fase β contribuye principalmente a la elevada resistencia de la aleación debido a la amplia gama de β-estabilizantes (V, Mo, Cr, Fe), su cantidad y efecto sobre el mantenimiento de la fase metaestable durante el transcurso del enfriamiento lento (por ejemplo, en el aire) de secciones grandes de forjados a estampa. Aunque la fase β dirige el procedimiento de The β phase mainly contributes to the high resistance of the alloy due to the wide range of β-stabilizers (V, Mo, Cr, Fe), its quantity and effect on the maintenance of the metastable phase during the course of slow cooling (by example, in the air) of large sections of forged to stamp. Although the β phase directs the procedure of
5 endurecimiento en la aleación, la resistencia se puede incrementar únicamente debido a la mayor resistencia de la fase α, cuya fracción general para esta aleación es del 60-70%. Para este fin, la aleación se forma con el α-estabilizante de circonio. El circonio forma una amplia gama de las soluciones sólidas con α-titanio, está relativamente cerca de ello a temperatura de fusión y densidad y aumenta la resistencia a la corrosión. 5 hardening in the alloy, the resistance can only be increased due to the greater resistance of the α phase, whose general fraction for this alloy is 60-70%. For this purpose, the alloy is formed with the zirconium α-stabilizer. Zirconium forms a wide range of solid solutions with α-titanium, is relatively close to it at melting temperature and density and increases corrosion resistance.
10 La aleación con circonio en el intervalo de 0,1-menos del 0,7% garantiza la combinación de la resistencia y plasticidad elevadas para forjados grandes y forjados a estampa así como semiproductos de sección fina, tales como barras, placas de un espesor de hasta 75 mm, permite realizar la deformación en caliente y en frío con la relación de recalcado de hasta el 60%. 10 Zirconium alloy in the range of 0.1-less than 0.7% guarantees the combination of high strength and plasticity for large slabs and forged slabs as well as thin section semi-finished products, such as bars, plates of a thickness up to 75 mm, it allows hot and cold deformation to be carried out with the highlighting ratio of up to 60%.
